Flight performance and planning
7.4.2.1 Take-off distance
When taking off in a tailwind, add + 20% per 10% of Vr (the rotational speed) the tailwind
constitutes.
Safety factor: Takeoff distance should be less than runway length x 0.7!
7.4.2.2 Landing distance
Landing distance from curves/tables (over 50 feet)…….. m.
Addition for: Wet short grass 20% m.
Wet solid snow / ice 50% m.
Dry solid snow / ice 20% + m.
Subtotal………
Reduction: *Headwind ÷ 1 % pr. current kt. ÷
Landing distance ………….
*This is compensated by only counting on 50% of the wind (in headwinds).
Do not land in tailwind
Safety factor: landing distance should be max. be 70% of the runway available
Remember. 10% too high landing speed gives 20% longer landing distance!
